Essay on Iron Ore : Nature, Classification and Production

Essay # Classification of Iron Ore: According to usage, function-ability and composition, iron ores are principally of four major types: A. Magnetite (Fe 3 O 4): It is the richest among all iron ores with little impurities. The iron content varies between 70 to 72.5%. It contains magnetic properties, therefore it is suitable for electrical ...

Iron - Wikipedia

Most of the iron in the crust is combined with various other elements to form many iron minerals. An important class is the iron oxide minerals such as hematite (Fe 2 O 3), magnetite (Fe 3 O 4), and siderite (FeCO 3), which are the major ores of iron. Many igneous rocks also contain the sulfide minerals pyrrhotite and pentlandite.

Iron Ore: Sedimentary Rock - Pictures, Definition More

The iron ore deposits began forming when the first organisms capable of photosynthesis began releasing oxygen into the waters. This oxygen immediately combined with the abundant dissolved iron to produce hematite or magnetite. These minerals deposited on the sea floor in great abundance, forming what are now known as the "banded iron formations
